Introduction
Not being able to hear someone during a phone call can be frustrating, especially when you need to have an important conversation. Sometimes the problem is simple, such as low volume or a blocked speaker, while other times it may involve software settings, Bluetooth connections, network issues, or hardware damage.
The good news is that many phone call audio problems can be fixed without professional repair. A few simple checks can help identify the cause and restore clear call quality.
This guide explains common reasons why you cannot hear calls on your phone and provides practical solutions for Android and iPhone users.
Check Your Call Volume First
One of the most common reasons people cannot hear calls is simply that the call volume is too low.
Your phone usually has separate volume controls for:
- Phone calls
- Media playback
- Notifications
- Alarms
Changing the volume while watching a video may not affect call volume.
How to Adjust Call Volume
During an active call:
- Make or answer a call.
- Press the volume-up button.
- Increase the volume until the sound is comfortable.
Make sure you adjust the volume while the call is connected because this changes the call audio level.
Check If Your Phone Is Connected to Bluetooth
Bluetooth devices can sometimes redirect call audio away from your phone.
Examples include:
- Wireless earbuds
- Car audio systems
- Smart watches
- Bluetooth speakers
You may not hear the caller because the sound is being sent to another device.
How to Fix It
Try:
- Turn off Bluetooth temporarily.
- Disconnect connected devices.
- Make another test call.
If call audio returns, the Bluetooth connection was likely the cause.
Clean the Phone Speaker and Earpiece
Dust, dirt, and debris can block the small speaker used for calls.
Over time, buildup can reduce sound quality and make calls difficult to hear.
Safe Cleaning Tips
Use:
- A soft, dry brush
- A clean microfiber cloth
- Gentle air movement
Avoid:
- Sharp objects
- Excessive moisture
- Pressing hard into speaker openings
Small amounts of debris can make a noticeable difference.
Restart Your Phone
Temporary software problems can affect phone audio.
A restart can help by:
- Refreshing system processes
- Closing stuck apps
- Fixing minor software errors
Restart Steps
- Hold the power button.
- Choose restart.
- Wait for the phone to turn back on.
- Test a phone call.
This simple step often solves temporary issues.
Check Do Not Disturb and Sound Settings
Some sound settings may affect how your phone handles calls.
Review:
- Do Not Disturb mode
- Silent mode
- Sound profiles
- Notification settings
While these settings usually do not completely block call audio, incorrect configurations can sometimes create confusion.
Turn Off Call Audio Enhancements Temporarily
Some phones include audio features designed to improve call quality.
Examples:
- Noise reduction
- Voice enhancement
- Equalizer settings
Occasionally, these features may cause problems.
Try This
Go to sound settings and temporarily disable audio enhancements, then test a call.
If the issue improves, one of these settings may need adjustment.
Check Network Signal Strength
Poor network conditions can affect call quality.
You may experience:
- Low volume
- Robotic voices
- Dropped audio
- Delayed conversations
Improve Call Quality
Try:
- Moving to an area with stronger signal
- Going outdoors
- Restarting your network connection
- Switching locations
If the problem only happens in one area, the network may be responsible.
Test Speakerphone Mode
Using speakerphone can help determine whether the issue is with the earpiece or the entire audio system.
Test
- Start a call.
- Turn on speakerphone.
- Check whether you can hear clearly.
Possible results:
- Speakerphone works, but normal calls do not: earpiece problem may exist.
- Both fail: software, network, or hardware issues may be involved.
Check If Headphones Are Causing the Problem
Sometimes phones mistakenly detect connected headphones.
Signs include:
- Call audio not coming from the phone speaker
- Headphone icon appearing unexpectedly
- No sound without accessories
Fixes
Try:
- Disconnecting headphones.
- Cleaning the charging or headphone port carefully.
- Restarting the phone.
Update Your Phone Software
Software updates can fix audio-related bugs.
Updates may improve:
- Call stability
- Device compatibility
- Speaker performance
Check for Updates
Go to:
Settings → System Update
Install available updates and test your call again.
Update Carrier or Network Settings
Some phones receive updates related to mobile network services.
These updates can improve:
- Calling features
- Connection reliability
- Voice service performance
If your carrier provides updates, install them when available.
Check App Interference
Some apps may affect phone audio.
Examples:
- Call recording apps
- Audio management tools
- Security apps
- Voice assistant tools
Troubleshooting Method
Try:
- Close recently installed apps.
- Restart your phone.
- Test a call.
If the issue started after installing an app, that app may be causing the problem.
Reset Network Settings
If call problems continue, resetting network settings may help.
This can fix issues related to:
- Mobile connections
- Wi-Fi calling
- Bluetooth connections
Remember that this removes saved Wi-Fi passwords and some network preferences.
Before Resetting
Make sure you know:
- Your Wi-Fi passwords
- Your Bluetooth device setup details
Check SIM Card Problems
A damaged or incorrectly placed SIM card can affect calling.
Possible signs include:
- Dropped calls
- Poor signal
- Call connection problems
Try These Steps
- Turn off your phone.
- Remove the SIM card if possible.
- Check for visible damage.
- Reinsert it correctly.
- Test calling again.
If problems continue, contact your mobile provider.
Check for Physical Damage
Hardware damage can affect phone audio.
Possible causes:
- Drops
- Water exposure
- Damaged speakers
- Internal component problems
Signs of hardware issues include:
- No sound from any app
- Distorted audio
- Crackling noises
- Problem continues after resetting software
Professional repair may be needed in these cases.
Try a Different Calling Method
Testing different calling methods can help identify the issue.
Try:
- A regular phone call
- A call through another app
- Speakerphone
- Wired or wireless headphones
This helps determine whether the problem is with:
- The phone hardware
- The network
- A specific calling feature

Frequently Asked Questions
Why can I hear music but not phone calls?
This may happen because call audio uses a different speaker and volume setting than media playback.
Why is my phone call volume suddenly low?
Possible causes include changed volume settings, blocked speakers, Bluetooth connections, or software issues.
Can a dirty speaker affect call sound?
Yes. Dust and debris can reduce the volume coming from the earpiece.
Why does speakerphone work but normal calls do not?
This usually suggests a problem with the phone’s earpiece speaker rather than the entire audio system.
Should I reset my phone if call audio stops working?
Try simpler fixes first. A reset should usually be considered only after other troubleshooting steps fail.
Conclusion
When you cannot hear phone calls clearly, the problem is often caused by a simple setting, connection issue, or temporary software problem. Checking call volume, disconnecting Bluetooth devices, cleaning the speaker, updating software, and testing different audio options can solve many common issues.
If basic troubleshooting does not work, the problem may involve the SIM card, network service, or phone hardware. Taking a step-by-step approach helps you identify the cause without unnecessary repairs.
With regular maintenance and careful settings management, you can keep your phone calls clear and reliable.
